DESCRIPTION

FIG. 1 illustrates a side view of an embodiment of the top portion ofthe multiple-part pile cap that can be attached to the frame of astructure. The multiple-part pile cap 100 includes a top portion and abottom portion that are configured to supply a mechanical interfacebetween a foundation pile providing a foundation for a structure and aframe of a structure itself, such as an electrical inverter mounted on askid in the field. The multiple-part pile cap 100 can include multipleangle brackets. The angle bracket, such as an L-shaped angle bracket, ofthe bottom portion of the multiple-part pile cap 100 is shown, mountedbetween the flanges of the foundation pile mated to the webbing inbetween the flanges. The bottom portion is mechanically secured to thefoundation pile with two hex head bolts with lock nuts and washers andthen torqued into place. For example, the hex head bolts can be torquedto, for example, 220 foot pounds on the webbing. FIG. 2 illustrates atop-down view of an embodiment of a foundation pile with its webbinginterior and protruding flanges. Referring to back FIG. 1 , themultiple-part pile cap's 100 bottom portion can be designed to fit andbe bolted and be torqued to a webbing/interior flat surface in betweenthe two protruding flanges of a foundation pile (e.g. I beam or H beampile cap) The webbing of the foundation pile (e.g. a W6 pile), can bemechanically secured to the frame of a structure through themultiple-part pile cap 100, all of which requires no welding; butrather, use of bolts and nuts and then torquing of those bolts.

FIG. 3A illustrates on the left-hand side a top-down view of the bottomportion of the multiple-part pile cap mated to the webbing with multiplebolts (e.g., two bolts) going through the webbing of the foundation pilewith the other flange of the angle bracket also having multiple holes inthat flange in order to mate up with a top portion of the multiple-partpile cap 100.

Note, a multiple-part pile cap 100 is configured to be installed ontothe foundation pile of a set of foundation piles driven into a ground toprovide the foundation for the structure using the multiple-part pilecap 100 as the mechanical interface between the foundation pile and theframe of the structure being secured to the foundation pile. Forexample, see FIG. 4 that illustrates a side view of an embodiment of astructure with a frame, connecting via the multiple-part pile cap 100 toan example two foundation piles driven into the ground.

On the right-hand side, FIG. 3B illustrates a side view of the bottomportion of the multiple-part pile and the top part of the multiple-partpile cap 100. The bottom portion has two bolts going through the webbingof the foundation pile. Note, due to the side view and both bolts beingparallel to each other only one bolt can be seen. The second boltpenetrating the webbing of the foundation pile is right behind the firstbolt.

Next, the upward flange of the angle bracket of the bottom portion ofthe multiple-part pile cap 100 mates to a flange of the top part of themultiple-part pile cap 100 with one or more bolts and nuts. Thus, theflange of the angle bracket of the bottom portion of the multiple-partpile cap 100 receives a bolt coming from the angle bracket of the topportion of the multiple-part pile cap 100 in order to mechanicallysecure the top and bottom portions of the multiple-part pile cap 100together. Note, also not shown are, in this example, one or more boltsgoing through the flange of the angle bracket making up the top portionof the multiple-part pile cap 100 into the frame of the structure thatis going to be secured to the foundation pile.

Referring to FIG. 3A, the bottom portion of the multiple-part pile cap100 is almost always an angle bracket that is matched in width to theinterior dimensions/webbing width of the foundation pile. The bottomportion of the multiple-part pile cap 100 can be i) matched in width toa width of a webbing of the foundation pile and ii) has one or moreholes in a first flange of the multiple-part pile cap 100 to be boltedto the webbing of the foundation pile. The bottom portion of themultiple pile cap is connected between the protruding flanges of thefoundation pile by being bolted through holes in the webbing of thefoundation pile. In general, the angle brackets will be manufacturedwith holes for passing one or multiple bolts in and through the anglebracket into a foundation pile. Note, when the foundation pile does nothave existing holes for the bolts to pass through, then holes can bedrilled through the webbing of the foundation pile.

Thus, the multiple-part pile cap 100 is configured to be installed onthe foundation pile. One or more foundation piles of the set offoundation piles are driven into the ground and have been cut relativethe other foundation piles in the set of foundation piles so that theportions of the foundation piles in the set of foundation pilesextending above ground level form a substantially level plane (e.g. + or−0.5 inches) for the frame of the structure being secured to a set ofmultiple-part pile caps corresponding to the set of foundation piles sothat the frame of the structure will be level when mechanically securedto the set of foundation piles. For example, see FIG. 4 illustrating aside view of an embodiment of a structure with a frame, connecting viathe multiple-part pile cap 100 to two foundation piles driven into theground. FIG. 5 illustrates a magnified view of the side view of FIG. 4at the point where a flange of a top portion of the multiple-part pilecap connects with bolts to a frame of the structure. FIG. 6 illustratesa top-down view of four example foundation piles, where each foundationpile with a multiple-part pile cap 100 attaches with the boltsprotruding through the webbing of its corresponding foundation pile andthe angle bracket of the bottom portion of the pile cap installed in theinterior along the webbing of the foundation pile. Each foundation pilehas been cut to be substantially level to each other.

Again, the multiple-part pile cap 100 can be bolted onto the webbing ofthe foundation pile, such as a wide flange I beam, and the equipment.For example, a structure such as an electrical inverter skid for solarpower can have 10 support foundation piles each. Four foundation piles,each with its own multiple-part pile cap 100 are shown in FIG. 6 . Themultiple-part pile cap 100 fits in the flange/webbing of, for example aW6 sized foundation pile, and holes can be drilled, e.g., by a magdrill, on the inside to install the holes. As a result, no welding canbe required to make the mechanical connection between the foundation andthe frame of the structure. Instead, the multiple-part pile cap 100 canbe attached to the foundation pile as the mechanical interface.

Note, as discussed later, the top portion of the multiple-part cap pilecan be adaptable/adjustable to match a size and/or shape of a frame ofthe structure/platform that the pile foundation is attaching to. Thebottom portion of the multiple-part pile cap 100 can connect to thefoundation pile (e.g., an I beam or an H beam). The bottom portion ofthe multiple-part pile cap 100 can be bolted to the foundation pile. Themultiple-part pile cap 100 can be connected to a frame of structures forany pile-mounted equipment, such as an inverter structure, a batterystructure, etc.

The multiple-part pile cap 100 can include an angle bracket such as anL-shaped bracket. The L-shaped bracket can include a horizontal surfaceand a vertical surface connected on one side. The horizontal surface andthe vertical surface can be substantially perpendicular to each other.Further, the vertical surface and the horizontal surface can includeholes. A set of bolts can attach the vertical surface to the foundationpile (e.g., an I beam) via a first set of holes. Another set of boltscan attach the horizontal surface to an angle bracket via a second setof holes. The angle bracket can be part of the equipment that is beinginstalled on the foundation pile.

The first and second sets of holes can be formed by punching through thevertical surface and the horizontal surface of the multiple-part pilecap 100.

Thus, a first flange of an angle bracket in the bottom portion of themultiple-part pile cap 100 can be mated to the webbing in the foundationpile. The first flange of the angle bracket is i) matched in width to awidth of the webbing and ii) has one or more holes in the first flangeto be bolted to the webbing of its corresponding foundation pile. Asecond flange of an angle bracket in the bottom portion of themultiple-part pile cap 100 can be bolted to a first flange of anotherangle bracket in the top portion of the multiple-part pile cap 100. Oneor more holes in the second flange of the angle bracket in the bottomportion are matched in location with one or more holes in the firstflange of the other angle bracket in the top portion when matedtogether. Thus, the bottom portion of the multiple-part pile cap 100 isbolted to the top portion of the multiple-part pile cap 100. The twobrackets are mated together with bolts, nuts, and washers. The top anglebracket can be shimmed as needed to ensure a solid connection betweenthe top of the foundation pile and the frame of the structure. Theequipment connections can be i) slotted or ii) have bolt holes to matchthe type of structure they are being installed on. The bolt size canchange accordingly to adjust size variations of different equipment anddifferent manufacturers. One or more washers, such as lock washers, canbe used to fill gaps between the bolts and the brackets of themultiple-part pile cap 100.

The bottom portion of the multiple-part pile cap 100 can be a firstangle bracket. The top portion of the multiple-part pile cap 100 can bea second angle bracket. The first angle bracket in the bottom portionand the second angle bracket in the top portion of the multiple-partpile cap 100 are attached together in opposite rotations. The anglebracket in the bottom portion and the angle bracket in the top portionof the multiple-part pile cap 100 can be seen as two 90-degree bracketsthat are attached together in opposite rotations. That is, if theL-shaped bracket is a right angle bracket, the angle bracket is a leftangle bracket that is attached to the horizontal surface of the L-shapedbracket.

The bottom portion of the multiple-part pile cap 100 is configured to bebolted to the top portion of the multiple-part pile cap 100, and then,the top portion of the multiple-part pile cap 100 is mechanicallysecured to the frame of the structure. The flange of the second anglebracket in the top portion of the multiple-part pile cap 100 can bebolted to the frame of the structure. Thus, when the frame of thestructure that is going to be secured to the foundation pile has a flatportion on its side that the angle bracket can mate up to, then theflange of the second angle bracket in the top portion of themultiple-part pile cap 100 is bolted to holes in that flat portion ofthe frame. The angle bracket of the top portion of the multiple-partpile cap 100 is rotated relative to the bottom angle bracket andconnects through bolt connections the bottom portion of themultiple-part pile cap 100 and the frame of the structure being securedto the foundational pile. Lastly, any bolted connections are configuredto be torqued to be seismically safe.

Again, once all the foundation piles are installed on the ground, themultiple-part pile caps 100 can be installed on the foundation piles.The multiple-part pile caps 100 create an overall surface, i.e., aplatform, for the equipment to be installed on. The foundation pile,i.e., a W6 pile, can be inserted into the ground in such a way that atleast portions of the foundation pile are located above the ground. Thepile-mounted equipment then can be attached to the pile foundation viathe multiple-part pile cap 100. The multiple-part pile cap 100 can thenbe used to connect the foundation piles to the equipment via the anglebrackets. The pile foundation and the multiple-part pile cap 100 canform a raised platform above the ground. In cases where the anglebrackets do not exactly fit on the multiple-part pile cap 100 and gapsare formed, washers can be used to fill the gap. That is, the washerscan be used to compensate for height variations. Additionally, if thereare no preexisting holes on the foundation piles, then holes can becreated by using a mag drill, and the brackets can be bolted to thefoundation piles.

In cases where the angle bracket includes pre-made holes, using washersand/or clamps can compensate for any possible height variations. Theholes on the vertical surface or the horizontal surface can be pre-madeor during the installation. By bolting the L-shaped brackets to thefoundation pile and the equipment, extensive welding can be avoided,which can save time and operational expenses.

In an embodiment, the angle bracket can have a first flange/horizontalsurface and ii) the vertical surface/a second flange that are used toconnect the multiple-part pile cap 100 to the equipment. Each of i) thehorizontal surface and ii) the vertical surface can include one hole ortwo or more holes.

The horizontal surface can be a cold rolled steel L-bracket, mounted inthe W6 web of the pile on both sides. The bolts on the horizontalsurface can fasten the surface to the foundation pile whether it be an Hbeam or an I beam. The angle bracket can be ½ inch to ⅜ inch thick steeland the bolts can be ¾ inch hex head coarse thread bolts.

Each bracket and flange can be hot dipped into galvanized finish toresist weather and rusting. The flange can be a protruded ridge, a lip,or a rim. Alternatively, the flange can be either external or internal,and serve to increase strength, make attachment/transfer of contactforce with another object easier, or stabilize and guide the movementsof a machine or its parts.

FIG. 7 illustrates a side view of an embodiment of an example threefoundation piles driven into the ground, where each foundation pile hasits own multiple-part pile cap 100 securing that foundation pile to theframe of the structure.

FIG. 8A illustrates on the left-hand side a top-down view of the bottomportion of the multiple-part pile cap 100 mated to the webbing withmultiple bolts going through the webbing of the foundation pile with theother flange of the angle bracket with a single hole in that flange inorder to mate up with a top portion of the multiple-part pile cap 100.On the right-hand side, FIG. 8B illustrates a side view of the bottomportion of the multiple-part pile and the top portion of themultiple-part pile cap 100. The bottom portion has two bolts goingthrough the webbing of the foundation pile and uses one bolt on theother flange to mate up to the top portion of the multiple-part pile cap100.

The cross-section of the horizontal surface can be uniform throughoutits length. In such embodiments, the horizontal surface is “inserted”into the I beam. That is, the flanges of the I beam are positioned on,i.e., the cover, both sides of the horizontal surface. In suchembodiments, the horizontal surface can include only one hole.Alternatively, comparing 8A to 2A, the cross-section of the horizontalsurface can change throughout its length. For example, while thehorizontal surface is “inserted” into the I beam closer to the verticalsurface, once the flange ends, the cross-section of the horizontalsurface enlarges, in such a way that the largest width of the horizontalsurface can substantially match the width of the flange. In suchembodiments, the horizontal surface can include two holes. The holes ofthe horizontal surface can be formed closer to the side of thehorizontal surface that is farther from the vertical surface.

FIG. 9A illustrates on the left-hand side, a top-down view of the bottomportion of the multiple-part pile cap 100, mating to the webbing of thefoundation pile via using bolts and lock washers and nuts going throughthe webbing to mechanically secure the bottom angle bracket portion tothe webbing, and then on the opposite flange of the angle bracket beingtwo slots in the opposite flange for connection to the clamp that isgoing to be forming the top portion of the multiple-part pile cap 100.On the right-hand side, FIG. 9B illustrates a side view of the topportion of the clamp clamping onto a flange of the frame of thestructure that is going to be mechanically secured to the foundationpile through the multiple-part pile cap 100. The bottom portion of themultiple-part pile cap 100 bolts to the top portion of the multiple-partpile cap 100. The top portion of the multiple-part cap pile is adaptablein form to match both a size and a shape of a frame of thestructure/platform that the foundation pile is attaching to through thetop portion of the multiple-part cap pile. A first flange in an anglebracket in the bottom portion of the multiple-part cap pile can bebolted to i) a first flange of another angle bracket in the top portionof the multiple-part pile cap 100 or ii) a clamp in the top portion ofthe multiple-part pile cap 100 to be mechanically secured to the frameof the structure being secured to the foundation pile. The top portionof the multiple-part pile cap 100 can be a clamp that mechanicallyconnects to the bottom portion of the multiple-part pile cap 100 andthen the clamp clamps onto a flange of the frame of the structure beingsecured to the foundational pile. FIG. 10 illustrates a side view of anembodiment of a rocking washer and bolt that act as a clamp for the topportion of the multiple-part pile cap 100 in order to clamp onto aflange of the frame of the structure that is going to be mechanicallysecured through the multiple-part pile cap 100 to the foundation pile.

Note, the bolted connections will be torqued to be seismically safe.

FIG. 11 illustrates a side view of an embodiment of when the frame ofthe structure that is going to be secured to the foundation pile merelyhas a horizontal flange on its side that a clamp can clamp onto, then aclamp is used as the top portion of the multiple-part pile cap 100. Aclamp is typically used when the frame of the structure is not allowedto be drilled into; and thus, a clamp clamps onto a flange of thatframe.

Other frames come with a part that can be bolted into (pre-existingholes in the frame) and then the angle bracket forming the top portionof the multiple-part bracket will bolt into that part of the frame thatcan be bolted into. When the top portion of the multiple-part pile cap100 is a clamp then the clamp will have a bolt run through the clampinto the bottom portion of the angle bracket and will be torqued. A slotis in the clamp version.

The angle bracket has two holes on the bottom portion's angle bracketthat connects to the webbing of the foundation pile. One slot is in theother flange of the bottom angle bracket for the clamp. The clamping canfacilitate installing equipment that needs elbow connections, e.g.,side-connection. The clamps, e.g., rocking washer, lindapeter clamps,etc. can include noses and tails. Each clamp can be so arranged on thevertical surface that the nose of the clamp is positioned above thehole. The bolt can be inserted via a hole in the nose of the clamp intothe hole of the vertical surface. If necessary, the height can beadjusted by a washer. A further washer can be used above the clamp tofurther adjust the clamp on the vertical surface and improve thestability of the multiple-part pile cap 100.

Note, the required amount of foundation piles needed for the structurebeing secured to the foundation piles is typically dictated by theweight of the structure itself and this can dictate whether the amountof bolt holes used in each flange.
